This certainly looks like an anterior STEMI (proximal LAD occlusion), with STE and hyperacute T-waves (HATW) in V2-V6 and I and aVL. How do you explain the anterior STEMI(+)OMI immediately after ROSC evolving into posterior OMI 30 minutes later? This caused a type 2 anterior STEMI.

This is a troponin I level that is almost exclusively seen in STEMI. So this is either a case of MINOCA, or a case of Type II STEMI. If the arrest had another etiology (such as old scar), and the ST elevation is due to severe shock, then it is a type II STEMI. I believe the latter (type II STEMI) is most likely.

It is equivalent to a transient STEMI. Not much, but studies of STEMI and NonSTEMI show that about 70% of those diagnosed with STEMI have a peak troponin I above 10 ng/mL and that about 70% of those diagnosed with NonSTEMI have a peak troponin I below 10 ng/mL. What is Spontaneous Coronary Artery Dissection (SCAD)?
